WHy i do this question? Becuase you can't put 2 before insert triggers at the same time (you can but is not cleany) I mean, if you want to do a 'control' of the inserted data i think is better a good trigger that filter data to insert, and if you want a log table make a rule or in the same function of the trigger put the logging

Just think: waht are the beneffits of this implementation? what do you want to resolve with it? > > Ketema J.
